Now, 96% of the U.S. population, or about 300 million people, have cellphones. If everyones risk of glioma went up 40% as a result of cellphone use, the number of gliomas in the U.S. would increase by 8,000. Thats a one in 40,000 increase in each persons risk of glioma, which still isnt very big.

But the study the WHO is citing only showed the 40% increase in the 10% of people who used cellphones most. I dont know how many people in the U.S. would now fall into this group, but wed be talking about maybe hundreds of cases spread out over the whole U.S. population.

The whole thing is worth reading, especially as he compares this to the risk of throat cancer from HPV...
